The tuner driver used to change i2c_client.name for its own needs, but
it really shouldn't, as this field is used by i2c-core to do the
device/driver matching. So, create and use a separate field for the
tuner driver needs.

Update all the remaining new-style i2c drivers to use standard module
aliasing instead of the old driver_name/type driver matching scheme.

Note that the tuner driver is a bit quirky at the moment, as it
overwrites i2c_client.name with arbitrary strings. We write "tuner"
back on remove, to make sure that driver cycling will work properly,
but there may still be troublesome corner cases.

The current code passes a context pointer in the xc5000_config struct.
This context pointer is used in the tuner_callback function, used to
reset the device after firmware download.

The xc5000_config struct is a static structure, whose .priv member was
being assigned before calling xc5000_attach().  If there are more than
one of the same device type installed on a single system, the last one
to assign xc5000_config.priv will "win", and all others will cease to
function properly.

This patch passes the context pointer in xc5000_attach() rather that
storing it within the static struct xc5000_config.

As pointed by Andrew Morton, the error testing were wrong. After reviewing
tea5767, it were returning a positive value for errors.

So, the double errors were cancelling each other.

This patch fix it properly. It also considers any positive value as ok, on
tuner-core.

This patch allows new-style i2c chip drivers to have alias names using

point, the old i2c driver binding scheme (driver_name/type) is still

set_addr log were almost useless: discarded SET_TYPE_ADDR commands weren't
reported.

This patch changed set_addr printk to print a message only if set_addr is
wrong.

It also fix printk at set_type, since, if an attach were failing, nothing
were reported.

With the current code, working or not, a call to set_addr will produce a debug
printk.

also, set_type() were producing a false error message on tuner_xc2028, since
it were requesting for setting a frequency on a place where firmware name
weren't set yet.

This patch removes zoran checks for VIDEO_V4L2, since this API is always
present, when V4L is selected.
Signed-off-by: NMauro Carvalho Chehab <mchehab@infradead.org>

The video_dev parameter, on tuner-xc2028 were used to pass i2c private data to
tuner_callback. Since the driver already have a pointer to i2c_adap->algo_data,
uses this instead.

This parameter were used also as a magic number to idenfity if two drivers are
trying to register the same xc3028 tuner. This occurs with boards with DVB
support, where both DVB and V4L drivers will share the same tuner.

Instead of using the algo_data as a private number, after this patch, the
driver will use i2c_adap->dev, with seems more consistent.

Move tuner type ID check from tuner-core::set_type to simple_tuner_attach.

Since tuner-core forwards all attach requests to tuner-simple as the
default case, unless a specific attach function is specified in
set_type, this change is an appropriate cleanup.

Rather than using a pointer, include struct analog_demod_ops directly
inside struct dvb_frontend.  This will allow us to use dvb_attach in
